Karakoram Highway Travel Guide - Free Web & App

The corridor followed by the modern Karakoram Highway belongs to a much older network of paths linking the Indian subcontinent with Central Asia and China. Caravans, pilgrims, traders and local communities used mountain passes and valley routes rather than one continuous engineered road. Gilgit-Baltistan’s position between the Hindu Kush, Karakoram and western Himalaya encouraged contact among different peoples, while rivers and narrow valleys concentrated settlement in otherwise rugged terrain. The route’s Silk Road association is therefore best understood as a broad historical connection rather than evidence of a single ancient highway following precisely the modern alignment.

Before modern state infrastructure, the upper valleys were governed through a mixture of local rulers, village communities and small mountain kingdoms. Hunza, Nagar, Gilgit and Baltistan each developed distinctive political and cultural traditions, while trade and migration connected them with Kashmir, Afghanistan, Central Asia and the regions to the east. Fortified residences such as Baltit and Altit reflect the strategic importance of Hunza’s valley routes. The modern highway passes through communities whose languages, architecture, agriculture and religious traditions remain closely connected to these earlier regional identities.

The northern mountain regions became increasingly important to British India during the nineteenth and early twentieth centuries because of their position near the frontiers of Afghanistan, Xinjiang and the princely states. Gilgit developed as an administrative and strategic centre, while routes through the mountains were surveyed and improved for military and political purposes. After the creation of Pakistan in 1947, the remote northern areas remained difficult to reach from the south. Transport was commonly dependent on narrow roads, tracks and air links, reinforcing the isolation of many valleys.

Construction of the modern highway began in the 1960s through cooperation between Pakistan and China and continued for more than a decade. The route required extensive surveying, bridge building, tunnelling and road cutting through unstable mountain terrain, with the loss of many workers during the project. It was opened to public traffic in the late 1970s and formally inaugurated in 1979. By linking Pakistan’s northern areas with the Khunjerab Pass and China, the road transformed trade, administration, communications and access to education, healthcare and tourism across communities that had previously been separated by difficult terrain.

The highway has brought economic opportunity and far greater visibility to destinations such as Hunza, Gilgit and Passu, while also increasing traffic, construction and pressure on water, waste and fragile mountain environments. The 2010 Attabad landslide in Hunza blocked the Hunza River and created Attabad Lake, temporarily severing the road and prompting the construction of tunnels and a lakeside realignment. Today, road maintenance, disaster response and environmental management remain central to travel along the corridor. Tourism is now an important part of the regional economy, alongside agriculture, trade, transport and public services.
